Anthropic has apologized for implementing hidden guardrails in its AI model, Claude Fable, which prevented users from distilling the model into competing systems. The company will now make these safeguards visible, routing queries to a previous model, Claude Opus 4.8, when the safety measures are triggered. This change comes after backlash from the AI research community, who argued that the hidden guardrails could affect third parties trying to evaluate the model. The decision to make the safeguards visible aims to balance human safety and cybersecurity needs.
